Letters Patent No. 106,110, dated AugustQ, 1870.

IMPROVED sorrow: ron TABLES.

The Schedule referred to in these Lettqrs Patent and making part of the same.

I, J AMES BLAKE, of the city of Scranton, county of Luzernc and State of Pennsylvania, have invented certain Improvements'in Auxiliary Tables or Supports, of which the following is a specification.

Nature and Object of my Invention.

My invention relates to the manner of securing anxiliary tables, adjustable platforms, or other supports to tables, sewing-machine stands, desks, shelves, 8m, the object of my invention being to secure the auxiliary-table, platt'orm oi' support, to the main table, shelf, &c., firmly and eflectnally, but easily, bymeans which will permit ready and easy detachment.

One form of my invention is shown in the drawing and specification of a patent granted to me, anddated March 23, 1869, numbered 88,121, and reissued November 2, 1869, to JAMES and Gnonon BLAKE, assignees of JAMES BLAKE, and numbered 3,697, wherein it is represented as a part of the supporting or attaching brackct, arm, hinge, or hanger 1).

Description of Accompanying Drawing;

Figure 5 isasjde elevation of the bracket D above referred to. A

Figure 6 is a side elevation of 'a modification of fig. 5, level with, the main table.

Figured} is a side elevation of still another modification, in which the two tables are on level and the stop function is performed by another pin, '11, above the pin a, engaging a similar recess.

, Figure 7 is a side elevation ot another form, with the'beak O resting under the edge of the table.

, Gciwral Description.

In ti". 5 the auxiliary support is held in place, or secured when put in place, by the combined action of the-beak O, recess (1, pin a, and the mere weight of the auxiliary table or support resting upon the beak ,O, as a fnlcrum,the eliect of which is to .clamp the parts-together, so as to prevent lateral or end mo- -l.'nfig. G'the bank 0, projection 11, and weight of the auxiliary, secure tlie same method of action and the same resulnhysubstantiall y thesame arrangement.

In fig. 6% this beak function is performed as in ti". 6, but instpad of the point ortprojection p, the pin 1),

of the upper bar of the slot b precisely like the recess d, in fig. 5, 860- This stop may varyin form and location, as in figs. 5, 6, 6%, and even fig. 7, where the hookh acts as the In fig. 7 there is no stop action at the end of the bracket, and no recess or projection, but the beak 0, being formed in a hook-shape, itself performs both the supporting and securing functions of the beak and the recess I, pin a, or projection p.

l I do not intend, by anything herein, to confine mydctails. Varying in form the stop may be moved from the position of the original recess 2 and pin it toward the beak, and at any point operate effectually and similarly.- It may even be revolved around the beak, as in fig. 7, becoming, when sorevolved a book, 71.

The hook it, manifestly, could be moved toward the. further end of the bracket on its under side. But in all these variations thcesscntial feature in accomplishing. the object of myinvention is the chi-operation of the beak with the stop in such a manner as to secure the auxiliary to the main table, under all the treatment it is likely to receive, except the onc'action 'oi' lifting the auxiliary, and thereafter drawing the same from the main table, when it may be droppedand hang under the table. This peculiar joint action of the the beak and stop may be styled co-operation or. co.- ordination, which constitutes the principle of this'my invention. So the beak may, by change in, its shape simply, perform both the functions of beak and stopo in co-ordinatlon.

" Claim.

I claim as my invention- An auxiliary table, provided with one or more beaks and one or more stops co-ordinated, for the pun pose of sccnringit in position, substantially as described and shown.
